3 months ago I decided to just look at my air filters and see how they were doing. I totally stripped one of the screws so I decided to just leave it alone until my 600 mile service. I took it to the only Yamaha dealership here in Bakersfield and was charged $ 123.00 for the service. Now at 2000 miles I decided to look at the filters again just to see how bad they might be. To my surprise the same stripped screw was still there. It turns out they never replaced the air filters at the 600 mile service. They would've had to replace that screw to get to it. I was charged for both filters. That dealership is now out of business and transferred all the Yamaha inventory to Valley Cycle, also here in Bakersfield. When they shut down, two of the four techs were kept on to go to work for Valley cycle. I went in there yesterday and asked to speak to the owner but was not there. I left a note for him explaining my experience I had and left him my number. (I haven't gotten a call and dont expect to.) I tell this long story just to let you know that you have to double check the work you pay for cuz you just never know if you're getting what you pay for. I have now followed the advice from this forum and made my own filters.....good luck to you all.
